颈胸段脊柱(cervicothoracic junction,CTJ)向上连接颈椎,向下延续胸椎,是脊柱的一个特殊部位,多指C7~T4[1-3]。CTJ周围有复杂、重要的组织结构,如大动静脉(主动脉、腔静脉等)、重要器官(肺脏、气管、食管、胸导管等)、神经结构(神经根、喉返神经等)、骨性结构(胸骨、锁骨等);在生物力学上,由前凸的颈椎过渡到后凸的胸椎,造成此处应力集中[4]。CTJ恶性肿瘤相对少 Cervical thoracic spine (cervicothoracic junction, CTJ) upward link to the cervical spine, continuing down the thoracic spine, is a special part of the spine, mostly refers to C7 ~ T4 [1-3]. CTJ is surrounded by complex and important tissue structures such as aorta and vena cava, vital organs such as lung, trachea, esophagus and thoracic duct, nerve structure (nerve root and recurrent laryngeal nerve), bone Sexual structures (sternum, clavicle, etc.); biomechanics, the transition from the anterior cervical spine to the kyphotic thoracic spine, resulting in stress concentration here [4]. CTJ cancer is relatively small
